Warm and very dry conditions are shrinking the flow of the Colorado River. With the meager snowmelt, the river's already depleted reservoirs will probably decline further this year.

Meager snowpack adds to Colorado River's woes, straining flows to Southern California
Melting snow from California's Sierra Nevada is filling reservoirs. But dry conditions have shrunk the flow of the Colorado River, straining a vital supply for Southern California.

We did the math: On Trump's order, two Central Valley dams released at least 2 billion gallons of water. It didn't help farms or Los Angeles. www.latimes.com/environment/... by @ianjames.bsky.social @jessicagarrison.bsky.social

I grew up in Altadena in my great-grandmother’s old home. The house is safe, but just a few blocks away is devastation.

Childhood friends lost their homes. Places I knew my whole life are gone.

I wrote about this special community with @brittnymejia.bsky.social + @melissagomez.bsky.social
Altadena had soul, solitude and community. Can those qualities survive devastating firestorm?
The Eaton fire cut a brutal swath through Altadena and a cherished way of life in this eclectic foothill community it upended.
